Job description

• Has distinction in Master degree.

The Manufacturing Metrology research group of the KU Leuven Department of Mechanical Engineering investigates, develops, optimises and implements measurement solutions for manufacturing quality control. Our expertise covers surface and 3D coordinate metrology using tactile and optical probes as well as X-ray Computed Tomography (XCT). We target Industry 4.0 readiness of measurement solutions by increasing speed, reducing measurement errors, and establishing traceability to realise in-line and in-process capabilities that intelligently feedback inspection results for first-time-right and zero-waste manufacturing. We put our expertise and state-of-the-art equipment at the disposal of manufacturing companies to address complex metrology challenges and to improve manufacturing process understanding and performance.

Responsibilities

X-ray computed tomography (XCT) is a non‑destructive volumetric imaging technology that can image both external and internal structures of parts. The technology has been increasingly used for industrial applications. However, the cost and time consumed to conduct XCT scans are significant for industrial use in the uptake of the technology. Hence, most XCTs are used for research rather than for production purposes.

Recent developments have demonstrated the potential of using XCT to assess the quality of battery cells. However, there is currently no guidance on how to perform dimensional evaluation for such specialised applications, and the impact of systematic influence factors and measurement errors remains largely unknown. This project aims to develop a robust data analysis workflow that converts XCT measurement outputs into reliable, interpretable quality metrics.

As part of this project, you will join a supportive team of research scientists working together to advance battery quality evaluation using XCT. You’ll have the chance to learn new skills, contribute your own ideas, and grow your expertise while shaping your future career path.
